The Chemical Composition of Secc Galvanized Cold Rolled Steel:
The chemical composition of the base metal of SECC steels as under which is probably the same as of SPCC steel:
Maximum percentage of Carbon(C) is 0.15
Maximum percentage of Manganese(Mn) is 60 percent.
Maximum percentage of Phosphorous(P) is 050 percent.
Maximum percentage of Sulphur(S) is 050 percent.
Remaining is iron (Fe) percentage and with few negligible impurities.
